This argument doesn't resonate with me at all.

Incentives are the key, or what is an individual incentivized, on a personal level to do.

Indie devs, inherently, due to their status want to finish the job fast and well. Fast, as they likely charge per project. And quality as they want a reference and repeat business.

Devs in corporations want to do the same as well. But some people, for different reasons could not be incentivized to be working fast. This is where good dev ceremonies, like Scrum, can unearth those with lower velocity and get them to produce at the pace the wider team needs them to.
